My baby has been making vomiting sounds since yesterday when she puts her hands in her mouth, and within an hour of doing so, she vomited. Please explain this and give me some good advice. please

A. A lot of kids have their teeth or they are in the process they usually keep their hands and finger into the mouth and because of that they vomit also and sometimes it could be due to poor digestion also so currently if you want you can introduce tablet number 21 under homeopathy and also teether bye babyhug
